      Conditions working fine for the first level keys:

      SELECT * FROM `test` 
      WHERE `data`->'$.node' > 1;
      

      Conditions works wrong:

      SELECT * FROM `test` 
      WHERE `data`->'$.orders[*].order_id' > 1;
       
      SELECT * FROM `test` 
      WHERE `data`->'$.orders[*].products[*].price' > 50;
       
      SELECT * FROM `test` 
      WHERE `data`->'$.orders[*].products[*].total' < 30;
